Vibrobot Saturday

Homage to Evil Mad Scientist.  We scuppered old motors from toy cars instead of using mobile pagers.  The manufactured track is from a Hexbug Nano set.

pH ART

A day at Chesterton Primary showing Year 2 kids how to make their own litmus paper using red cabbage.

Chop and boil the cabbage for 10 min, then paint the dark red juice onto blotting paper.  Leave it to dry, or warm very gently in oven.  When it's dry, you can cut it into strips.

Children painting with lemon and bicarb

Use the strips for testing various liquids - try milk, oven cleaner, lemon juice, baking soda, saliva etc.

The children numbered their strips and wrote down what they had tested.  When they went back to class, they did a presentation and explained how some things are acid, some are alkali and some are neutral.

At home, we used lemon juice, bicarbonate of soda and tea as finger paints.

Rude Cats

Clips from toy theatre project, using TAGS hidden in the puppets and an RFID reader in the cottage.  The cats make different comments depending on who approaches.  Lots of fun making puppets and voicing cats.

 

Using Processing to play audio files, triggered via Arduino (with RFID reader) connected through serial port.  The cats have a range of responses for each tag, so the output is randomised.  You can hear the same audio clip being invoked more than once so the sounds overlap.
